lMPRGVEMENT lid GENERAL JOlNERS.

Specification forming part of Letters Patent No. 130,651, dated August20, 1872.

Specification describing a new Improvement in General Joiners, inventedby DAVID H. WILLIAMS, Sr., of Paris, in thc'county of Bourbon and Stateof Kentucky.

Figure 1 represents a vertical longitudinal section of my improvedwood-working machine. Fig. 2 is a top view of the same. Fig. 3 is afront elevation, and Fig. 4 a side elevation, of the same.

Similar letters of reference indicate corre spondin g parts.

The invention consifts in working lumber across a wood-working machine,by means substantially as hereinafter described.

A in the drawing represents the supportingframe of the machine. Forordinary purposes it does not require more than about four feet inlength and three in width. It is built of substantial woodwork,sufficiently strong for the work to be done on it. B isa horizontalcarriage, fitted between two horizontal guide rails, a a, on the upperpart of the machine, and connected with a lever, C, which is pivoted tothe frame A, and serves to. adjust the carriage back or forward, in themanner described. D is a horizontal shaft hung lengthwise in thecarriage B, to receive at its front end the lathe-chuck, circular, rip,or cross-cutsaw, or other tool to be revolved. The shaft D is, by meansof a belt, 12, connected with a drum, E, hanging in the lower part ofthe frame A, and receiving rotary motion by suitable mechanism, so thatthe shaft D will also be turned. F is a longitudinal adjustable restplaced upon two rails, cl (1, of the frame A, so that its center pin 6will be in line with the axis of the shaft D. It can be clamped to therails 01 by means of a screw, f, nut g, and lower The carriage B has atits sides projecting screws '11 i, which fit through slots in the railsto a, and have nuts 7, whereby the carriage can be fastened in suitableposition. G G are verticallyadjustable side plates, placed at the sidesof the frame A, upon a longitudinally-adjustaole frame, H, which has wedge-shaped projections l, fitting corresponding recesses or inclinededges of the plates Gr. When the frame H is, by means of a screw, I,

moved backward the plates G G will he elevated, and they will be loweredwhen the frame H is moved forward. The plates G G are slottedvertically, as shown, and guided on pins on m.

On a machine made as thus far described, nearly all ordinary turningwork can be done, both regular and irregular; so also all sorts ofdrilling and boring. The usual or convenient rests, gages, 800., may beemployed during such operations.

When the machine is to be used for sawing, a table, J, is placed overthe frame B, and clamped in front by screw-clamps n to the plates G,while at the rear it will be supported on vertical pins 0 0, which standon the plates G, so that such table will be adjusted up and down by andwith the plates G. A shifting rail, L, may be placed over the table J toguide the planks or things to be ripped by the saw. 'When the machine isto be'used for cross-cutting, a transversely-sliding frame, M, is placedover the table J, and supports the article to be cut. By projecting ribs19 at the ends, the frame M is so guided on the table J as to carry thework in a straight line across the operating saw. With the aid of thevertical adjustment of the table J ,this machine can be used for allkinds of sawing by circular saws.

It will be unnecessary to enumerate all the possible functions of thismachine. They are almost unlimited. By applying proper cutterheads tothe shaft D and using the table J, tonguing, grooving, planing, molding,and all manner of Work can be performed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- The carriage B, shaft D, plates G G, and

frame H, combined and arranged on the frame A of a wood-working machine,as described, for the purpose of working the lumber across the machine,as set forth.
